1 Claim. (01; 15-214) This invention relates to eyeglass cleaners and wipers and it has particular reference to a pocket type device of this character.

The principal object of the invention is to provide a case, preferably of molded plastic, in which is arranged a transverse partition to define compartments in each end of the case, one to accommodate a receptacle containing a glass cleaning fiuid while the other compartment retains a glass wiper consisting of a pair of Wiping discs of any suitable material and of concavo-convex cross-section to conform to most types of lenses, said discs being mounted on individual arms, constrained under their own inherent resiliency, to spring outward upon withdrawal of the discs from the case, the latter operation being made possible by virtue of a mounting for the arms slidably disposed on suitable guides in the case.

Another object of the invention is to provide a convenient medium for use in cleaning eyeglass lenses, worn by those required to work under conditions requiring frequent cleaning, and particularly, a device possessed of both utility and pleasing external appearance and so designed as to avoid undue bulkiness in the pocket and will impose no unusual wear thereon.

With the foregoing objects as paramount, the invention has further reference to certain features of accomplishment which will become apparent as the description proceeds, taken in connection with the accompanying drawings wherein:

Figure 1 is a perspective view of the case of the invention with both end caps shown as being detached.

Figure 2 is an elevational view with one side section of the case removed and showing the fluid receptacle in cross-section.

Figure 3 is a vertical section taken on line 3-3 on Figure 2.

Figure 4 is a perspective view of the wiper assembly, per se, and

Figure 5 is a diametrical section of the wipers taken on line 5-5 on Figure 4.

Continuing with a more detailed description of the drawing, reference is primarily made to Figure 1 wherein numeral [0 denotes a case, preferably of ellipsoidal cross-section and made up of two parallel sections secured together. The case is preferably made of plastic and in molding, shoulders I3 arc defined adjacent each end as stops for caps l4 and I5 for the cleaner and wiper ends respectively, of the case. In molding, the sections of the case are so designed as to provide transverse webs [6 intermediate their ends which l 2 jointly become a partition when the sections are in assembled relationship. Thus, the case is divided into two compartments, one being adapted to receive a conforming receptacle I! for containing a suitable liquid known to possess glass cleaning qualities whilethe other compartment encloses the wiping elements, to be referred to in more detail presently.

The liquid cleaner container I! has ,an opening in one side, normally covered by a screw l8, by which it is filled with liquid. The exposed end of the container which receives the cap I 4 has an orifice l9 therein, which, when not in use, is plugged by a pin 20 carried by the can,

when the latter is in position, to prevent leakage of liquid from the container ll.

Referring again to the wiping elements, it will be observed in Figure 3 particularly that a substantially V-shaped ridge 2| is provided on. each inwardly formed edge of one of the case sections. These ridges are in confronting relationship to be conformably received by correspondingly shaped grooves 22 in a cross-head 23, formed on or attached to a pair of resilient arms 24, extending laterally therefrom towards the end of the case. The cross-head or arm mounting 23 is operatively disposed in transverse relation to the major axis of the case and, of course, slides to and fro in the compartment allotted thereto. It is first installed by turning it at an angle with respect to the guiding ridges 21 and when aligned therewith, it is moved upright to embrace these ridges, with the arms 24 parallel with the longitudinal axis of the case.

The drawing shows the arms 24 as being of resilient material which may also be plastic, and which are sprung outwardly from each other and constrained to lie in l'uxtapositioned relationship only by confinement in the case and when pulled outwardly, they will spring apart so that a lens may be conveniently inserted between. the discs 26.

The discs 26 each carry a removable pad 21 of any material suitable for cleaning glass and when soiled, the pads may be replaced by new ones. Any type of fastening means suited by the purpose may be employed for securing the pads in place.

It is apparent from the foregoing that to clean a pair of eyeglasses, the cap I4 is first removed and a drop of fluid shaken thereon from the receptacle H. The cap 14 is replaced and cap l5 removed and the lens inserted between the pads 21, which have been drawn from the case. The particular lens conforming shape or the discs renders wiping easy and insures against the likelihood of imposing too great pressure of the lens in wiping. When the glasses have been cleaned, the wiping arms are thrust back into the case, the cap replaced and the case returned to the pocket.

In Figure 1, thumb and finger recesses 28 are provided to facilitate withdrawal of the wiper assembly. A V v p Manifestlm; the {corlistr'uction{as shown and de; scribed is'capablepf some modification and such modification as may be construed to fall within the scope and meaning of the appended claim is also considered to be within the spirit and intent of the invention.

What is claimed is: i

An eyeglass lens wiping deyice, including ahollow case formed by complementary sections and having an elongated opening in one end of said case, a cross-headlocated in said case and havin o twar y O in r ov s n opposite edges iher ofyw h wnerate with, and, slidin ly en ae 'Vr hap d i s: form d. on the nterior of.;.said,,case and -whic-h extend longitudinally of said case,. .a; pair of arms of resilient material; as apted -to normally spring outwardly from; each 4 other when projected from said case and formed by extensions of said cross-head which project longitudinally of said case and of a size to pass through the elongated opening in said case, shoulders at each edge of said elongated opening to limit sliding displacement of said cross-head and retain said cross-head within said case, and a lens wiping pad mounted on the end of each of said arms.
